Seattle police are asking for the public's help finding the hit-and-run driver who killed Michael Wang, who was struck while riding home from his job at a nonprofit health organization.

The collision occurred at 3:44 p.m. July 28 near Dexter Avenue North and North Thomas Street.

Detectives are looking for a mid-1990s to mid-2000s beige or brown American-made SUV, possibly with tinted windows and a silver luggage rack. There may be slight or moderate front end damage or no visible damage, Detective Jeff Kappel said.

"TCIS detectives are looking for any information related to this incident as well as witnesses who have not yet spoken to police," he said. Anyone with information – even someone wanting to remain anonymous - is asked to call (206) 684-8932.

A doctor who was in the area when the bicyclist was hit stopped and performed CPR before the first medics arrived, fire department spokesman Kyle Moore said. Wang, a married father of two, died at Harborview Medical Center.

"It's just a feeling of complete, deep sadness and loss," Fay Venegas, his co-worker told our news partner, KOMO/4. "He was always true to himself. He had deep passion."

Wang, 44, would ride his bike to work every day and often come to the office in cycling gear, she said.

He started work at PATH seven years ago as a temporary mail clerk and later became a facilities assistant responsible for handling building management issues.

Colleagues remembered him as a talented photographer who created iconic photos of the organization's work on projects in Bolivia, Kenya, Nicaragua and Ukraine. Portraits he took cover the walls of PATH's offices. Click here to see a slideshow of Wang's work.
